Blood Type Impacts COVID-19 Susceptibility and Severity

Additional clinical evidence published on October 14, 2020, suggests a person's blood type may play a role in COVID-19 susceptibility. A new study from Denmark found blood group O is associated with a decreased risk for contracting SARS-CoV-2 infection.

And, a second study found COVID-19 patients with blood group A or AB appear to exhibit a greater disease severity than patients with blood group O or B.
